The invention discloses a surveying and mapping equipment quick disassembly and assembly connector for an unmanned aerial vehicle. A locking groove is formed in a locking clamp, a sliding groove communicated with the locking groove is formed in the locking clamp, a clamping block is arranged in the sliding groove, an inserting hole is formed in the clamping block, and a step shaft is inserted intothe inserting hole so that the step shaft can move along with the clamping block and can rotate relative to the inserting hole; threads are arranged on the step shaft, a threaded hole is formed in the locking clamp; a spring sleeves on the step shaft between the side wall of the clamping block and the side wall of the sliding groove; during use, the locking clamp only needs to be installed on theunmanned aerial vehicle, surveying and mapping equipment is installed on the locking block, quick disassembly and assembly can be achieved, limitation of the type of the unmanned aerial vehicle is avoided, meanwhile, when the locking clamp locks the locking block, the male socket can be meshed with the female socket, and the power source of the unmanned aerial vehicle supplies power to the surveying and mapping equipment on the locking block, an independent power supply does not need to be mounted on the surveying and mapping equipment, and thus the connector is simple in structure and more practical.
